IMPROVED ATTACHMENT FOR CONVERTING OTHER FLUID INTO COAL-OIL LAMPS.

Specification forming part of Letters Patent No. 37,987, dated March 24, 1863.

' plied to a lamp; Fig. 2, a detached front or back view of the same; Fig. 3, a plan or top view of the same applied to a lamp.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to a new and simple contrivance which maybe applied to the tube of an ordinary burning'fluid lamp for the purpose of rendering the same capable of burning coal-oil without the aid of a draft-chimney.

The invention consists in having two curved prongs, perforated at their upper ends, forked at their lower ends, and attached to a clamp which is so constructed and arranged that it may be fitted on the wick-tube and adjusted or raised and lowered thereon, so that the upper perforated parts of the prongs may be placed in a proper relative position with the top of the wick-tube as may be required to insure perfect combustion.

To enable those skilled in the art to fully understand and construct our invention, we will proceed to describe it.

A A represent two prongs, which are constructed of sheet metal curved at their upper parts, and of cup form, as shown at a a, the concave sides being underneath, as shown in Fig. 1. These parts a a are perforated, and they are so curved as to have nearly a horizontal position. The lower parts of the prongs are slotted vertically so as to havetwo arms,-

I) b, which are curved and are secured at their lower ends to a clamp, B, which is formed of two plates, 0 c, riveted or otherwise connected together near their ends, and curved or bent at their center, as shown at (I, so as to form an opening to admit of the clamp being fitted on the wick-tube O of the lamp. The portions of the plates 0 c at each side of the opening form springs to keep the clamp in close contact with the wick-tube and prevent the casual sliding or slipping of the former on the latter. The outer or upper edges of the parts a aof the prongs A A are not in contact, a space being allowed between them equal in width to the diameter of the wick-tube C, and the device is adjusted on the wick-tube in such a position that the parts a a will be about oneeighth or three-sixteenths of an inch above the top of the wick. By this arrangement the base of the flame is spread so as to receive the air, and the latter is allowed to pass freely to the flame in any direction. Consequently the lamp may be moved about without danger of being extinguished; The perforations in the parts a a of the prongs admit of a current of air passing laterally to the flame.

The invention may be applied to the lamps of lanterns, as well as to ordinary hand-lamps.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

The two prongs A A, provided at their upper parts with pertorated cap-shaped terminals, and slotted at their lower parts to form arms I), which are connected to a suitable clamp, all arranged as and for the purpose herein set forth.
